Wireless communication device and communication pairing method thereof

Abstract

A wireless communication device includes a device body, a wireless radio frequency receiver and a paring program. The device body includes a wireless radio frequency transmission module and a Bluetooth transmission module. The wireless radio frequency receiver is connected with a host and receives a wireless radio frequency signal from the wireless radio frequency transmission module. A device descriptor about the device body is stored in the wireless radio frequency receiver. The paring program is installed in the host. The paring program performs a Bluetooth communication pairing process of pairing the Bluetooth transmission module with the host according to the device descriptor and a broadcasting information from the device body.

What is claimed is: 
     
         1 . A wireless communication device, comprising:
 a device body comprising a wireless radio frequency transmission module and a Bluetooth transmission module;   a wireless radio frequency receiver connected with a host and receiving a wireless radio frequency signal from the wireless radio frequency transmission module, wherein a device descriptor about the device body is stored in the wireless radio frequency receiver; and   a paring program installed in the host, wherein after the wireless radio frequency receiver is connected with the host, the paring program is executed to actively read the device descriptor from the wireless radio frequency receiver and judge whether the Bluetooth transmission module has been paired with the host according to the device descriptor, wherein if the paring program judges that the Bluetooth transmission module has not been paired with the host, the paring program performs a Bluetooth communication pairing process of pairing the Bluetooth transmission module with the host according to the device descriptor and a broadcasting information from the device body.   
     
     
         2 . The wireless communication device according to  claim 1 , wherein if the pairing program judges that at least a portion of the broadcasting information complies with at least a portion of the device descriptor, the paring program performs the Bluetooth communication pairing process of pairing the Bluetooth transmission module with the host. 
     
     
         3 . The wireless communication device according to  claim 1 , wherein the broadcasting information is continuously broadcasted from the device body, or the broadcasting information is periodically broadcasted from the device body, or the broadcasting information is broadcasted from the device body according to a prompt message from the paring program. 
     
     
         4 . The wireless communication device according to  claim 3 , wherein the device body is switched from a wireless radio frequency communication to a Bluetooth communication mode according to the prompt message from the paring program, and the broadcasting information is broadcasted when the device body is in the Bluetooth communication mode. 
     
     
         5 . The wireless communication device according to  claim 1 , wherein the device descriptor includes at least one of a vendor identification code (VID) of the wireless communication device, a product identification code (PID), a product string, a serial number, a vendor-defined protocol and a Bluetooth (BT) address, or the broadcasting information includes at least one of a vendor identification code (VID) of the wireless communication device, a product identification code (PID), a product string, a serial number, a vendor-defined protocol and a Bluetooth (BT) address. 
     
     
         6 . The wireless communication device according to  claim 1 , wherein the wireless radio frequency transmission module is a 2.4G wireless transmission module, and the Bluetooth transmission module is a Bluetooth low energy (BLE) transmission module. 
     
     
         7 . The wireless communication device according to  claim 1 , wherein the wireless communication device is a mouse device, a keyboard device, a writing tablet, a camera device or a wearable device, or the host is a desktop computer, a notebook computer or a tablet computer. 
     
     
         8 . A communication pairing method for pairing a device body of a wireless communication device with a host, the communication pairing method comprising steps of:
 (a) storing a device descriptor about a wireless communication device into a wireless radio frequency receiver of the wireless communication device, wherein the wireless radio frequency receiver receives a wireless radio frequency signal from the device body;   (b) reading the device descriptor from the wireless radio frequency receiver when the wireless radio frequency receiver is connected with the host;   (c) judging whether a Bluetooth communication pairing process of paring the device body with the host has been successfully done according to the device descriptor; and   (d) if the Bluetooth communication pairing process of paring the device body with the host has not been successfully done, performing the Bluetooth communication pairing process of paring the device body with the host according to the device descriptor and a broadcasting information from the device body.   
     
     
         9 . The communication pairing method according to  claim 8 , wherein if at least a portion of the broadcasting information complies with at least a portion of the device descriptor in the step (d), the Bluetooth communication pairing process of pairing the device body with the host is performed. 
     
     
         10 . The communication pairing method according to  claim 8 , wherein in the step (d), the broadcasting information is continuously broadcasted from the device body, or the broadcasting information is periodically broadcasted from the device body, or the broadcasting information is broadcasted from the device body according to a prompt message from the paring program. 
     
     
         11 . The communication pairing method according to  claim 10 , wherein the device body is switched from a wireless radio frequency communication to a Bluetooth communication mode according to the prompt message from the paring program, and the broadcasting information is broadcasted when the device body is in the Bluetooth communication mode. 
     
     
         12 . The communication pairing method according to  claim 8 , wherein the device descriptor includes at least one of a vendor identification code (VID) of the wireless communication device, a product identification code (PID), a product string, a serial number, a vendor-defined protocol and a Bluetooth (BT) address, or the broadcasting information includes at least one of a vendor identification code (VID) of the wireless communication device, a product identification code (PID), a product string, a serial number, a vendor-defined protocol and a Bluetooth (BT) address. 
     
     
         13 . The communication pairing method according to  claim 8 , wherein the wireless communication device is a mouse device, a keyboard device, a writing tablet, a camera device or a wearable device, or the host is a desktop computer, a notebook computer or a tablet computer.
